Mail traffic accounting

[ispcomm]

I missed something: When external mail arrives for a forwarded account do you count the size * 2 ? That is... 1MB arrives and 1MB leaves to the forwarded account. 2MB total for this email should be added to the domain.

I'll try to propose a simpler solution for amavis-on case. It assumes that deliveries to amavis will be on consecutive lines (probably true 99% of the time):

-) Count all deliveries to 127.0.0.1, but skip consecutive lines of the same value (i.e. the multiple recipients of the same mail).

-) Ignore all virtuals (they were accounted for on step 1).

-) Count all other SMTP traffic, mapping every destination address to the domain that forwarded it.

Another issue: What happens when a delivery is deferred?
